Macros
#define	GET_BIT(v, b)   (((v) >> (b)) & 0x1)
	Return true if bit b of v is 1.
#define	BIT_SET(v, b)   ((v) |= (1 << (b)))
	Set bit b of v to 1.
#define	BIT_CLR(v, b)   ((v) &= (~(1 << (b))))
	Set bit b of v to 0.

Functions
void	AsebaVMSendExecutionStateChanged (AsebaVMState *vm)
	Send an execution state changed message.
void	AsebaVMInit (AsebaVMState *vm)
	Setup the execution status of the VM. More...
uint16	AsebaVMGetEventAddress (AsebaVMState *vm, uint16 event)
	Return the starting address of an event, or 0 if the event is not handled. More...
uint16	AsebaVMSetupEvent (AsebaVMState *vm, uint16 event)
	Setup VM to execute an event. More...
void	AsebaVMStep (AsebaVMState *vm)
	Execute one bytecode of the current VM thread. More...
void	AsebaVMEmitNodeSpecificError (AsebaVMState *vm, const char *message)
	Can be called by glue code (including native functions), to stop vm and emit a node specific error.
uint16	AsebaVMCheckBreakpoint (AsebaVMState *vm)
	Execute on bytecode of the current VM thread and check for potential breakpoints. More...
void	AsebaDebugBareRun (AsebaVMState *vm, uint16 stepsLimit)
	Run without support of breakpoints. More...
void	AsebaDebugBreakpointRun (AsebaVMState *vm, uint16 stepsLimit)
	Run with support of breakpoints. More...
uint16	AsebaVMRun (AsebaVMState *vm, uint16 stepsLimit)
	Run the VM depending on the current execution mode. More...
uint8	AsebaVMSetBreakpoint (AsebaVMState *vm, uint16 pc)
	Set a breakpoint at a specific location. More...
uint16	AsebaVMClearBreakpoint (AsebaVMState *vm, uint16 pc)
	Clear the breakpoint at a specific location. More...
void	AsebaVMClearBreakpoints (AsebaVMState *vm)
	Clear all breakpoints. More...
void	AsebaVMDebugMessage (AsebaVMState *vm, uint16 id, uint16 *data, uint16 dataLength)
	Execute a debug action from a debug message. More...
uint16	AsebaVMShouldDropPacket (AsebaVMState *vm, uint16 source, const uint8 *data)
	Return non-zero if VM will ignore the packet, 0 otherwise.
